NAME

       "Tickit::SingleChildWidget" - abstract base class for widgets that contain a single other widget

SYNOPSIS

        TODO

DESCRIPTION

       This subclass of Tickit::ContainerWidget acts as an abstract base class for widgets that contain exactly
       one other widget. It enforces that only one child widget may be contained at any one time, and provides a
       convenient accessor to obtain it.

CONSTRUCTOR

   new
          $widget = Tickit::SingleChildWidget->new( %args )

       Constructs a new "Tickit::SingleChildWidget" object. If passed an argument called "child" this will be
       added as the contained child widget.

METHODS

   child
          $child = $widget->child

       Returns the contained child widget.

   set_child
          $widget->set_child( $child )

       Sets the child widget, or "undef" to remove.
